--------------------------------

commit a79343dc upstream.

Device-managed resources allocated post component bind must be tied to
the lifetime of the aggregate DRM device or they will not necessarily be
released when binding of the aggregate device is deferred.

This is specifically true for the DP IRQ, which will otherwise remain
requested so that the next bind attempt fails when requesting the IRQ a
second time.

Since commit c3bf8e21 ("drm/msm/dp: Add eDP support via aux_bus")
this can happen when the aux-bus panel driver has not yet been loaded so
that probe is deferred.

Fix this by tying the device-managed lifetime of the DP IRQ to the DRM
device so that it is released when bind fails.
